Help in setting up plugins and integrating the theme of the site on WordPress

There is a blog on child education on WP. The site works on a template, in addition to articles and information, it is expected to sell author's manuals. For this purpose, we installed and partially configured woocommerce – everything is well integrated (basket, checkout, my account), but the product catalog page and the product itself – as always terrible – the bar website goes down and the white background disappears. All the instructions found on the Internet failed to help – either there is no result – or the entire site falls into a white screen. Help is needed for reasonable remuneration.

Also on the site you need a closed paid section with a time limit (for example, a month) – for this purpose, you found a plugin, but have not yet bought. In this section, you need to show pictures of 100 pcs per day - implement by means of plugins, such a display (while open) does not work out. Accordingly, help is also needed.


I'm happy to answer all the questions.
